Abstract

It is currently important for the Ukrainian space industry to ensure the competitiveness of rocket and space complexes using launch vehicles in the global space services market. Launch  vehicles  are  considered  as  potential  carriers for  the  creation and implementation of satellite systems in accordance with national programs of Ukraine and other countries. An analysis of the design features of the existing spacecraft compartments shows that these systems were designed to work with pressure-tight  spacecrafts when only the temperature and humidity is monitored in the compartment. In the  work are performed   consideration, analysis and possibilities of air drying in pre-start thermostating systems to the required dew point. In the case of a slight increase in pressure, it becomes possible  to efficiently use Freon refrigerating  machines to  dehumidify  air to  a dew point below 0°C, instead of traditional physic-chemical dehydrators or high-pressure air drying in the starting systems for the thermostating of space rocket systems.
